Phosphogypsum-based concrete and preparation method thereof
The invention discloses ardealite-based concrete and a preparation method thereof, and belongs to the technical field of road engineering materials, the ardealite-based concrete comprises the following raw materials by weight: 70-75 parts of ardealite; 10 to 15 parts of cement; 7-15 parts of fly ash, 0.1-5 parts of quick lime and 0.1-1 part of a polycarboxylic acid high-performance water reducing agent. The preparation method comprises the following steps: crushing the ardealite, the fly ash and the quick lime by using a small crusher, and sieving until the particle size is less than 0.15 mm; and uniformly stirring and mixing the sieved phosphogypsum, quicklime and fly ash with cement and a water reducing agent to obtain the phosphogypsum-based concrete. According to the ardealite-based concrete and the preparation method thereof, the industrial waste residue ardealite is used in the concrete, the cement use cost is reduced, and an ardealite resource recycling mode is provided.
本发明公开了一种磷石膏基混凝土及其制备方法，属于道路工程材料技术领域，以重量份数计，包括以下原料：磷石膏，70‑75份；水泥，10‑15份；粉煤灰，7‑15份、生石灰，0.1‑5份，聚羧酸高性能减水剂0.1‑1份。制备时，将磷石膏、粉煤灰和生石灰经过小型破碎机破碎处理后，过筛，至粒度小于0.15mm；然后将过筛后的磷石膏、生石灰、粉煤灰与与水泥以及减水剂搅拌均匀混合在一起，即得磷石膏基混凝土。本申请采用上述的一种磷石膏基混凝土及其制备方法，将工业废渣磷石膏使用于混凝土中，减少使用水泥的成本和供一种磷石膏资源再利用的方式。
